Definitions
- the invention relates to a method for applying a finish to cakes of yarns or filaments, and particularly to an apparatus for carrying out a'method wherein the finishing solution is applied to the cakes of yarns or filaments and extracted therefrom with a minimum of dilution.
- cakes of freshly formed or regenerated cellulose yarn are subjected to various treatments, as for example desulphurizing and washing, before being passed through a series of finishing baths. From the finishing treatment, the cakes are centrifuged to remove the excess wash water and finishing solution, after which the cakes are dried, as for example by hot gases, while the extracted effiuent is conducted to at least the first of the series of finishing baths and serves as an intermediate bath for subsequent cakes of yarn undergoing the process.
- the continuous fiow of effluent to the intermediate bath necessitates a constant sewering of some of the liquid therefrom, and thus results in a substantial loss of finishing solution.
- Another object of the invention is to provide a method wherein the finishing solution is applied to the cakes of yarn after a major portion of the washing liquid has been extracted therefrom.
- Still another object is to provide a method wherein the finishing solution can be applied to a number of cakes of yarn without any substantial dilution.
- a further object is to provide a method for applying finishing solution to cakes of yarn which eliminates at least one of the method steps presently employed.
- a still further object is the provision of a method for yarn finishing which is simple and results in a substantial saving of materials.
- Fig. 1 is a perspective illustrating the apparatus employed in carrying out the method of the present inventron
- Fig. 2 is a top view of a portion of the structure shown in Fig. 1, illustrating the various stages of the process and the relative duration of each stage;
- Fig. 3 is a vertical section through the finish solution feed box taken along the line III-4H of Fig. 2.
- the invention in general, relates to a method of applying za finishing treatment to cakes of yarn.
- the cakes after their final washing, are centrifuged to extracta major portion of the wash liquid, and are then treated with a finishing solution which is subsequently extracted and recovered for reapplication to the other cakes of yarn to be treated.
- the finishing solution By applying the finishing solution, with the apparatus of the present invention, to the cakes of yarn after removal of the major portion of the final wash water, the extracted finishing solution remains substantially undiluted, and in addition eliminates the finishing step employed in the conventional method for which further washing and drainage of the cakes can be substituted.
- the apparatus for which the method of'the present invention is designed is generally similar to that disclosed in the US. Patent 1,986,434 toHarrison et al. and in- 'cludes a plurality of centrifugal buckets 5 (corresponding to the buckets 51 in said above noted patent) revolving about a common center and each rotating independently of the others about its own axis.
- the buckets are continuously revolved about the common center so that a different bucket 5 enters a loading and unloading position A approximately every 4 seconds, during which time an operator removes the centrifuged cakes from the buckets and inserts wet cakes therein.
- the buckets when loaded with cakes after their final wash, but before the finishing solution is applied, are independently rotated for a period substantially less than the 56 second period noted above toremove the major portion of the wash water.
- This stage of the process is designated as Bin Fig. 2 and is of a duration of approximately 28 seconds, during which time about 1.2 pounds of water per pound of finished yarn is extracted from each cake, whichiweigh approximately 1.413 pounds after drying and conditioning. From stage 8, the buckets pass into C at which time the bucket motors are turned ofi and the buckets gradually slow down in speed.
- stage C is approximately 6 secends in duration and is sufficient tozretardthe buckets'so that they can be suitably braked'during an approximately 15 second period shown as stage D in Fig. 2.
- stage D the finishing solution is applied individually to each of the buckets by structure hereinafter described.
- stage B the buckets are individually rotated about their axes to distribute the finishing solution through the cakes of yarn and to remove the excess finishing solution as they pass through the stage E, which takes about 28 seconds.
- Stages F and G are similar to stages C and D described above, during which time the bucket motors are not energized and the buckets are braked to a standstill as they approach the unloading stage A.
- the top cover 7 of the housing 9 is provided with an additional opening 11, approximately diametrically opposite the usual top cover loading and unloading opening 13.
- the opening 11 is located above the central or terminal section of the stage D so that the finishing solution can be applied to the cakes after the buckets each have been braked to a stop.
- a finishing solution feed box 15 partitioned at 16 to provide compart rnents 17 and 18, the latter of which has at its lower end, a suitable discharge opening or slot 19, adjustable as by a sliding plate, through which the finishing fluid is passed as the buckets pass thereunder.
- the compartment 17 serves as a reservoir from which the finishing solution overflows along the partition 16 to provide a constant flow of finishing solution through the slot 19.
- a conduit 20 connects the feed box 15 with the fluid circulating lines 21 and 23 which serve as the feed and return lines, respectively, for the finishing solution from the supply and makeup tank 25.
- a circulating pump 27 is provided in the feed line 21 and can be isolated from both the conduit 21 and the tank 25 by cutoff valves 29, while the conduit 20 and the return line 23 are provided with a control valve 31 and a pressure regulating valve 33, respectively, to enable fluid flow adjustments.
- the tank 25 is preferably equipped with a mixer 35 to maintain the finishing solution suitably agitated.
- the operator at stage A inserts the wet cakes of yarn into the buckets 5 as they revolve passed the opening 11. These cakes weigh approximately 4.9 pounds after being removed from the final wash treatment.
- the individual bucket motors are energized and the buckets are each rotated about its own axis to whiz out approximately 1.2 pounds of water for each pound of finished yarn.
- the rotary motion of the buckets is retarded and finally stopped as the buckets are revolved through stages C and D, with the finishing solution being applied to the cakes of yarn by the feed box, and related mechanism, as the buckets revolve through the final portion of stage D.
- stage E the buckets are again each caused to rotate about its own axis in the same manner as during stage B, to pass the finishing solution through the cakes of yarn and to centrifuge out the excess finishing solution which is collected and conducted to the supply and makeup tank 25.
- stage F and G once again causes the buckets to be retarded and finally stopped as they approach the stage A, where they are removed and ready for final drying.
- the method of applying a finishing treatment to a plurality of cakes of yarn after their final washing consisting of revolving said plurality of cakes about a common center, individually rotating each of said cakes about its own axis during a first portion of its revolving path to remove the excess wash liquid therefrom, retarding and stopping the rotational movement of each of said cakes during a. second portion of its revolving path, applying a finishing solution onto each of said cakes during said second portion of its revolving path, and individually rotating each of said cakes during a third portion of its revolving path to distribute the finishing solution through said cakes and to remove the excess finishing solution therefrom, said first and third portions of said revolving path each including an angle of less than 2.
- the method of treating a plurality of cakes of yarn after the final washing consisting of revolving a plurality of cakes about a common center, rotating each of the cakes of yarn to extract the excess wash liquid from the cakes concomitant- 1y as the cakes are revolved through a first arcuate path, sequentially applying a treating solution to each of said cakes as they pass through their revolving path, and rotating each of the cakes of yarn to distribute and remove the excess treating solution concomitantly as the cakes are revolved through a second arcuate path, said first and second arcuate paths each including an angle of less than 180 and being approximately equal in duration.
